| dc.description.abstract | 本論文研究中，成功的合成出雙咪唑離子液體和N-烷基咪唑修飾矽倍半氧寡聚物之離子液體。後者並以穿透式電子顯微鏡和粒徑分析儀加以分析，測得其在固相和液相中所呈現粒子的尺寸，可見出此種奈米複合材料有很明顯的團簇現像。利用雙咪唑離子液體和N-烷基咪唑修飾矽倍半氧寡聚物之離子液體作為染料敏化太陽能電池的電解質添加物，會增加電解液的黏滯度，反而降低了太陽能電池的效能；矽倍半氧寡聚物離子液體尤其具有高黏滯度。N-丁基咪唑修飾矽倍半氧寡聚物離子液體的甲醇溶液，會與乙酸乙酯溶劑分層，離子液體甲醇層沈積於下。此時如以超音波震盪，可以觀察到下層溶液中離子液體包覆甲醇氣體之氣泡的形成，氣泡受到乙酸乙酯的浮力逐漸上升，包覆甲醇氣體表面的離子液體逐漸變薄，呈現動態的互動。 | zh_TW |
| dc.description.abstract | Reported in the manuscript is the synthesis of diimidazolium-based ionic liquids and N-alkyl imidazoliums immobilized on POSS (polyhedral oligomeric silsesquioxane). The latter consists of eight propyl alley imidazolium chloride functional groups extending from the cubic silsesquioxane core. There POSS immobilized ionic liquids have been analyzed with transmission electron microscope and particle size analyzer. There the nanocomposites shown obvious aggregation.Diimidazolium-based ionic liquids and POSS immobilized ionic liquids have been tested for usage in electrolyte for DSSC (dye-sensitized solar cellxed with methanol). The high viscosity of POSS immobilized ionic liquids in electrolyte reduces the efficiency of cells. The mixture of POSS immobilized ionic liquids (with terminal N-butyl imidazoliums) and methanol was precipitated on ethyl acetate. The POSS immobilized ionic liquids forms bubbles filled with methanol vapors upon supersonic agitation and the bubbles arise to the top surface of the ethyl acetate when the POSS immobilized ionic liquids contanting enclose the methanol vapers. | en_US |
